Yes. The Sinclair Programmable -- which looks like a Sinclair Oxford, but has a very limited program memory (24 steps) that is not preserved on power off. Despite this, the calculator came with a large program library. I have one of these in my drawer, it works, but due to inaccuracies, or rather, imprecision, it is little more than a collector's item.

Thanks for the hint! I just secured one off ebay UK
Would you happen to have the documentation for it? My example will come as the bare calculator.

I saw at least two Czerweny (or some similar spelling) RPN machines in the early 90s, I think they where LED based at least one of them, the one that wasn't programmable. They were supposedly produced in Argentina, too.
